What the Record Tells You
Apex Diagnostics INC. is an NPI registry record for a radiology clinic/centre at 8205 Cass Ave Ste 108C in Darien, Illinois 60561. CMS issued NPI 1154949329 on 14 July 2020, and the organisation last updated its own entry on 6 July 2026. That is recent, so the contact details are likely current.
The record carries one imaging taxonomy code: Radiology clinic/center (261QR0200X). It registered as a radiology clinic without the MRI-specific code, so ask which modalities it operates before assuming an MRI is available. One other imaging record shares this street address: Complete Diagnostics INC.
Darien sits in the Chicago-Naperville-Elgin, IL-IN metropolitan area (DuPage County), which has 416 imaging-centre records on the Illinois side in the October 2026 file, 89 of them with the MRI code, out of 528 across Illinois. The nearest alternatives in the registry are Complete Diagnostics INC (0.0 miles, Darien), Midwest Open MRI. INC (0.5 miles, Darien) and Smart Choice MRI LLC (3.5 miles, Bolingbrook), with 2 more within 4.9 miles.
For a cash-pay benchmark, our Illinois freestanding-centre estimate is $550 to $1,600 for a typical single-region MRI. At Illinois hospitals the cash price is measured rather than estimated: $254 to $4,532 for a brain MRI, median $1,505, from 47 of the 61 Illinois hospitals whose own price files we have read, out of 114 in the state, files dated to September 2026. This centre's own prices are not in the registry: call (877) 589-1424 with the CPT code for your scan and ask for the self-pay rate, whether the radiologist's report is included, and the scanner's field strength.
What Medicare Paid This Centre (2024)
From CMS's public Medicare claims data for Apex Diagnostics INC. (NPI 1154949329). Each row is a scan the centre billed to Medicare for at least 11 patients in 2024.
| Scan | Medicare-approved amount | Centre's billed charge | National median approved |
|---|---|---|---|
| Abdominal ultrasound, complete CPT 76700 · 37 Medicare scans | $119 | $435 | $109 (647 centres) |
The Medicare-approved amount is the full amount Medicare accepts for the scan: its own payment plus the patient's share (usually the 20% coinsurance). The billed charge is the centre's own list price on those claims, which Medicare does not pay. Both are averages over the year, and the national column is the median approved amount across every centre that billed Medicare for that scan outside a hospital.
Neither figure is a self-pay quote. If you are paying cash, ask the centre for its self-pay rate for your CPT code and whether the radiologist's report is included.
Source: Centers for Medicare & Medicaid Services, Medicare Physician & Other Practitioners - by Provider and Service, 2024 data, read 15 October 2026. CMS does not publish a centre and scan with fewer than 11 Medicare patients, so a scan missing here may still be offered.

Cash-Price Benchmark
What to ask when you call
- The self-pay price for your exact CPT code (70551 brain, 72148 lumbar spine, 73221 or 73721 joint, without contrast), and whether the radiologist's report is included.
- Scanner field strength (1.5T or 3T) and whether it is closed, wide-bore or open.
- ACR or IAC accreditation, and who reads the images. The registry cannot tell you either.
- Whether they accept an order from a telehealth referral if you have no local doctor.
